Fluids have no definite shape and can flow, distinguishing them from solids.
Pressure in a fluid varies with depth and is the same at a given height in a fluid at rest, as per Pascal's law.
Bernoulli's principle explains the relationship between pressure and fluid velocity along a streamline.
Pressure is defined as the force exerted per unit area and is a scalar quantity.
Viscosity is the measure of a fluid's resistance to deform under shear stress or flow.
Bernoulli's principle states that in a steady flow, the sum of the pressure energy, kinetic energy, and potential energy remains constant along a streamline.
Surface tension is the energy required to increase the surface area of a liquid due to the cohesive forces between liquid molecules.
